Remember all those times your parents threatened to pull the car over and leave you by the side of the road if you didn't cut the crap? One Park Avenue lawyer actually made good on that threat Sunday night, and now she's in trouble with the law. Police say Madlyn Primoff, a partner at the white-shoe law firm Kaye Scholer in Manhattan, ejected her squabbling 10 and 12-year-old daughters from the family car Sunday, some three miles from her $2 million Scarsdale home.

According to the Daily News, the 12-year-old caught up to the vehicle and Primoff drove her home, leaving the younger girl to fend for herself on the mean streets of White Plains. Luckily, a good Samaritan spotted the girl in tears about 7:30 p.m., bought her ice cream and then flagged a cop.

Shortly afterward, Primoff reported the girl missing to the police, but when she came to pick the kid up at the station, cops booked her for endangering the welfare of a child. At her arraignment Tuesday, a judge issued a temporary order of protection barring her from seeing her children; she pleaded not guilty and was released. Her lawyer, Vincent Briccetti, tells the Post his client is "a great mother connected with a great family." That may be, but Primoff probably shouldn't count on breakfast in bed this Mother's Day.
